I am not a huge fan of undiscoverable keyboard shortcuts in general, but I especially think we should not be throwing open a web browser window to a third-party site when someone hits a keyboard key. If we want something similar, I think a buffer dialog would make a bit more sense, but I'm not sure how practical an F1 help key is, anyway—it feels like a really old pattern that isn't consistently used in apps these days.
